Added Summonings and Superior Summoning

[Archaeik]

The language between these two seem to interact in an unintended way

15th level Abyssal Sorcerer bloodline power
Added Summonings (Su): At 15th level, whenever you summon a creature with the demon subtype or the fiendish template using a summon monster spell, you summon one additional creature of the same kind.

Superior Summoning
You can summon more creatures.
Prerequisites: Augment Summoning, caster level 3rd.
Benefit: Each time you cast a summoning spell that conjures more than one creature, add one to the total number of creatures summoned.

this implies that whenever you use a summon for 1 creature, you get a 2nd, and then a 3rd (and a 4th if it's also your spell perfection)

I was thinking for awhile this could be empowered too, but I guess since there's no roll...
(although, that's not how I personally think empower should be, which is neither here nor there)

any thoughts?
this is still very powerful for summoning lesser creatures at 1d3 or 1d4+1 as it's still a gain of 2, potentially 3, which DO interact with empower

How are you seeing an unintended interaction? Just from the power aspect?

If so, yes it can be powerful. Now add the augment summoning feat, and profit. :)

I believe the intent of superior summoning was to never meant to apply to highest creature list. I'm pretty sure they meant "without bonuses from other sources"
(especially if it is indeed affected by spell perfection, which by current wording it should be)

but hey, I'll take it if there's no complaint

These two feats don't interact as stated. The "2nd" summon isn't coming from a summoning spell, it's coming from Added Summonings, a supernatural ability.
